SPECIFICATION formingpart of Letters Patent No. 560,108, dated June 20,1893.

Application filed January 17, 1891. Renewed June 14, 1892. Serial No.436,661. (No model.)

To all whom it may concern:

Be it known that I, HENRY ALEXIS WIL- LIAMS, a citizen of the UnitedStates, and a resident of Taunton, in the county of Bristol, Stateuseful Improvement in Wire-Rolling Mills, of which the following is aspecification.

My invention relates to so-called continuous train rolling mills inwhich the rolls are arranged alternately in oppositely inclined planesfor being placed at right angles to each other successively, and isdesigned more especially for facilitating the reduction of wire rods tosmall wires in the cold rolling process, but is applicable also invarious respects for roughing or breaking down rolls such as areemployed for reducing blooms or billets to wire rods as hereinafterfully described, reference being made to the accompanying drawings inwhich- Figure l is a fronttelevation of my improved wire rolling millwith some parts in section. Fig. 2 is a plan view of a portion of themill including two pairs of rolls and the gearing for applying thedriving power, with some parts in horizontal section. Fig. 3 is alooking in the direction of the axis of the rolls of one pair. Fig. 4 isa plan view of a guide for conducting the rods or wires from one pair toanother of the rolls. Fig. 5 is an end elevation of said guide. Fig. disa plan view of the upper part of the guide inverted. Fig. 7 is an endelevation of said part represented in Fig. 6. Fig. E} is a plan view ofthe lower part of the guide with a reducing guide at the delivery end,half of which is shown detached and inverted. Fig. 9 is an end elevationof the part represented in Fig. 8. Fign 10 is a plan view of part of thereducing guide modified so as to extend into the angle between therolls. Fig. ll is a front elevation, and Fig. 12 a side elevation of amodified form of the rod-gaging attachment. Fig. 13 is an end elevation,Fig. 14. a side elevation, and Fig. 15 a plan view of a modified form ofguide to be used between the respective pairs of rolls. Fig. 16 is alongitudinal section of one of the roll shafts and transverse section ofthe rollhousingsshowing the means of adjusting the rolls lengthwise foralignment of the passes. Fig. 17 is a front elevation of housings andtoothed wheels coupling a pair of rolls showing a modified arrangementof adjusting devices for the rolls. Fig. 18 is a front elevation of anadjusting key employed in the arrangement of Fig. 17.

On the bed plate or fgame a, which is to be of sufficient length for theentire train of rolls of which there may be twelve to fifteen pairs orsets more or less, I place at intervals corresponding to the distanceapart which it is desired to have the pairs of rolls, the transversetriangular base supports b, for the individual pairs or sets of rolls,the sides of which are at right angles to each other and forty fivedegrees to the horizontal plane, and one side of each is extended at 0,above the apex of the two. sides a suitable length for supporting theroll housings on the upper side of the incline so as to be geared at thelower side with the driving shaft said base supports being placed withtheir extending sides 0, in the opposite inclinations alternately. Thesebase supports may be cast together with the bed plate a, if desired, butfor convenience of handling it will probably be preferred to make themseparately and bolt them to said bed plate.

On the upper part c, of each base support is a pair of grooved reducingrolls d, mounted in housings e,]", of which the partf, is preferablymade integral with the bench g, the other e, being detachably fastenedto said bench for facilitating the application and removal of the rolls.The gear housing 72., is also supported on this bench and is alsopreferably made integral with it. The bench is used to support thehousings at a suitable height above the supporting base a, to affordspace between the housings and the said supporting base for theintermediate shaft 2', and its upper bearing j, said shaft being gearedwith the lower roll shaft 7c, by the spur wheel Z on the latter and thepinion m, on shaft 2', and itself being geared by the bevel wheels 91.,with the line-shaft 0, at one side of the base, two such shafts beingemployed one on each side for gearing with the rolls of the differentinclines, and both being geared with the main driving shaft 19, throughthe pinion g on said driving shaft and the spur wheels 3, on the saidline shafts. The roll housings are thus mounted on the intermediatebench, and the intermediate shaft is used to gear the rolls with theline shafts to facilitate the application of the step bearing and thewater circulating connection, and also the friction device. all inconnection with the lower roll shaft described farther on, whichcouldnot well, be employed if the said shaftwere geared directly withthe line shaft. The lower roll shaft 7c, has its lower end bearing inthe 'standard t, resting on one of the sides of the triangular basesupports 1), and below the apex of the same, said shaft having'thepinion 23 fast on or made integral with it andbeing continuous throughthe lower roll'and hav-f ing its upper bearing in the removablerollfhousing c, with the adjustable end thrust orf step bearing to, for thelower end, in the bored) hole of the standardand confined by the cap *0,screwed on the neck w, of theistan'dard for a means of adjusting thestep as the shaft is; shifted lengthwise from time to time foralignmentof the pass grooves with. packing rings? at w and y, adapted form'akingwater tight joints between the end of the rotating shaft and thestepbearing u,said bearingand die:

Theupper roll'shaft is also continuous and has its pin- "ion23 fast on it,same as the'lower one, and is bored for the circulation of waterwh'ichenters the upper end throughipipe 11, and escapes from the lower endthrough the thrust bearing elbow 9.

They are "fitted able collar 16, andthe nut 16 whichclutchesj the roll fast and "being removed allows theroll to be changed.

For adjusting the rolls Ipropose to utilizef the upper-"and lowerjournal boxes 17, in the? housin gs f'and h,whieh I-arrange so thatthey; can shift lengthwise alongthe shaftto'a liin-i it'ed extentwithmeans for forcing the outer; endsa'ga'inst the pinions 23;which mayconsist' of the cone pointed thrust studs 18 placed in suitable chambersin the-:housings with their heads behind the'side flanges wet the",bearings overlapping the housings, with the cone pointed adjustingscrews-20, screwing in through the sides of the housings against; saidpoints of thestuds so as to thrust them against the flanges of the boxesand-cause them to shift the clutch collars and the rolls,

or the same can be done by making the box flanges taper as representedin Fig. 17 and using wedge yokcs 21, that, may be'forced in between 'thehousings and the flanges by ad-.

owing to the-close proximity to the boxes,

where it would be difficult to work the set screws.

- Thespur wheel l,bywhich the lower roll jshaft7c,-is-driven,is madefastto the shaft by a friction device consistingof the friction collar24andcone 25, the co'nesocket 26 in the hub of the wheelgand theadjusting nuts '27 screwed onthe shaft to adjust the cone, the object"of which is toallow thewheelto shift and avoid stretching the rod orwire too much whenit may happen thatthe elongation of the rod or wire isnot equal to the increased speed of the rolls towhieh therod or wire ismoving, over' the speed of the rolls from whi'ch itisissuing, Withs'u'cha f'ric-' tion clutch to-each pair of rolls except the first it isdesigned to speed therolls a little faster than the speed of the rods orwires so thatthey will always bet-aut'between the rolls and will runthrough straight tubular guides from'one pair of rolls to another, but-as-it willsometimeshappen that the rods or wires will getstalled in theguides so that ing the "hingejoint lugs3l, and the other has the forkedlugs'32 for hinging themto'gether, and both have forked lugs as33by'which to fasten-them with the bolts '34=hinged in the IOO S readyaccess for clearing out the obstruction llO forks of the part28and'adapte'd to'swin'g into theforks of part 29 ,,"to be clamped" fastwith "said bolts 34,whenfclosed in a mannei' adapt ed forreadilyfastening and -'unfastening thein.

passes.

10' to extend into the angle between the rolls close to where the rodsor wires enter the With such reducing guides of diflerent sizes theguide ways may have the bore large enough for the largest sizes, and beadapted for all sizes. I

Instead of the arms for fastening the guide to the housings it may havethe standard 30, as in Figs. 13 and 14 mounted on a shaft 30 that may beextended along the train of rolls in suitable bearings under the benchesor formed together with them.

It vwill be seen that whenever any obstruction occurs in the guide wayit may be quickly and easily unfastened for opening by slacking the nuts24 and swinging down the bolts.

The chief difficulty in the way of uniformity of reduction andelongation of the rods or wires, and the consequent variations in thetension and occasional overrunning and clogging of the wires in theguides is mainly due to the variations in the sizes of the rods as theycome from the rod mill, but to some extent also to the differentqualities and conditions of the metal which I have found can be greatlyrelieved by the employment of one or more pairs of gagin or sizing rollsin advance of the drawing rolls, by which I mean rolls that are notgeared and through which the rods are pulled by the reducing rollsbehind them, and I have therefore represented in this case a pair ofsuch rolls at 39 and 40 immediately in front of the first pair of rollsd, said rolls being in this case mounted in a housing frame 41, seatedon the projecting edge 42 of the bench g, the upper roll 40 being fittedin a frame 42 which is suspended by pivots 43 from the boxes 44 fittedin the vertical slide ways 45 in the upper part of the housing with theadjusting screws 46 to set said boxes, and the said upper roll, withsprings 47 under the boxes to hold them up to the screws. The purpose ofthis swinging device is to allow of opening the rolls to enter the rodsto begin with without changing the adjusting screws, as must be donewhen the screws are the only means of openingthem, and which is very objectionable because of the difficulty of restoring them to the exact gageas before with the screws, while in this arrangement the gage havingonce been fixed by the screws the roll returns to exactly the sameposition and the gage remains the same. In this case the rods areinserted through the open gaging rolls into the first pair of reducingrolls so as to be gripped sufficiently to be drawn forward after thegaging rolls are closed. Ihave in this example only represented one pairof gaging rolls but it is obvious that twoor more pairs may be employedif desired, in which case they will be placed in the same line and alsoat right angles to each other like the reduc- I have represented theupper sizing or gaging roll as the one adapted for swinging open, but itis obvious that it may be the lower one if preferred. a

It is not necessary to have the roll swing for opening and I do notlimit myself to that arrangement because it may slide back and forth aswell, as I have represented it in Figs. 11 and 12 where the'eeeentricrolls 48 are interposed between the adjusting screws 46 and boxes 44,suitably for being "shifted by lifting the handle 49 so that the spring47 may lift the roll to the desired extent for opening them, and thefall of the handle will shift said eccentric rolls and close the sizingrolls. It is ob vious that other means of opening and closing saidsizing rolls may be employed.
